IMM2902

IMM2902 is currently the only CD47×HER2 bispecific molecule that has entered into clinical stage globally. Our IMM2902 is being developed for the treatment of HER2-positive and HER2-low expressing solid tumors. IMM2902 suppresses tumor cell growth and proliferation through the blockade of HER2 and CD47/SIRPα inhibitory signals as well as the promotion of HER2 degradation, and further destroys tumor cells through enhanced innate immune responses.



Our preclinical studies demonstrated strong antitumor activities of IMM2902 in a variety of breast and gastric tumor models, including those with HER2-low expression and resistant to trastuzumab. We are conducting a Phase Ia/Ib clinical trial in China to evaluate IMM2902 in advanced HER2-positive and HER2-low expressing solid tumors, including breast cancer (BC), gastric cancer (GC), non-small cell lung cancer (NSCLC) and biliary tract cancer (BTC), with the first patient dosed in February 2022. IMM2902 was shown to be safe and well tolerated up to 2.0 mg/kg. Dosing is ongoing for higher dose level cohorts. We have also initiated the clinical trial for advanced HER2-positive and HER2-low expressing solid tumors in the U.S. with the first patient dosed in June 2022. We have received the Fast Track Designation from the FDA in July 2022.
